Feed additives are valuable tools for maintaining digestive health and efficiency. Yeasts and rumen buffers like sodium bicarbonate help to increase and stabilize dry matter intake as well as increase growth of the rumen microbes and improve fiber digestion. With higher dry matter intake, cows digest a greater percentage of their diet in their intestines. Bacterial direct-fed microbials can help to improve the cow’s balance of intestinal bacteria and enhance digestion as well as control the growth of undesirable bacteria and the toxins that they produce. Improvements in cow comfort, management, and nutrition have enabled many dairy producers to achieve high production while minimizing digestive dysfunctions and maintaining body condition.
